Calcium Supplements May Be Associated with an Increased Risk for Dementia, Study Finds

Researchers reported an associated risk between calcium supplementation and the development of dementia in women with cerebrovascular disease. But the study authors and independent experts said the five-year population-based study sample was too small and the findings are premature and need to be replicated in a larger study.

Aerobic Exercise Found to Improve Cognition in Mild Vascular Cognitive Impairment

Investigators reported that, in a randomized controlled trial, patients with vascular cognitive impairment showed improvement on cognitive tests after participating in a six-month exercise program. Independent experts said the findings were promising, but preliminary.

Progressive aerobic-exercise training for six months appeared to improve cognition in adults with mild subcortical ischemic vascular cognitive impairment,

Distinct brain networks underlie cognitive dysfunction in Parkinson and Alzheimer diseases

Objective: To determine whether cognitive impairment in Parkinson disease (PD) and Alzheimer disease (AD) derives from the same network pathology.

Methods: We analyzed 18F-fluorodeoxyglucose PET scans from 40 patients with AD and 40 age-matched healthy controls from the Alzheimer’s Disease Neuroimaging Initiative and scanned an additional 10 patients with AD and 10 healthy controls at The Feinstein Institute for Medical Research to derive an AD-related metabolic pattern (ADRP) analogous to our previously established PD cognition-related pattern (PDCP) and PD motor-related pattern (PDRP).
